Troubleshooting & Fixes

Video Buffering or Loading Slowly

SxyHub streams videos via BunnyCDN's global network using HLS (HTTP Live Streaming), which automatically adapts quality to your connection speed.

  1. Check your internet speed — you need at least 5 Mbps for 720p, 10 Mbps for 1080p.
  2. Switch to a lower quality setting by tapping the settings icon on the player (if available).
  3. Move closer to your WiFi router or switch from WiFi to mobile data (or vice versa) to test.
  4. Close other bandwidth-heavy applications (streaming, downloads).
  5. Clear your browser cache: Chrome → Settings → Privacy → Clear browsing data → Cached images and files.

Black Screen with Audio

You hear audio but see a black video frame:

  • Browser GPU issue: Try disabling hardware acceleration. Chrome: Settings → System → Use hardware acceleration when available → toggle off → relaunch.
  • Video still processing: Check if the video status is "Live" (a video thumbnail only appears after processing completes).
  • Outdated GPU drivers: Update your graphics drivers (Windows: Device Manager; macOS: Software Update).
  • Try a different browser to isolate the cause.

No Audio / Silent Video

  • The video player may be muted by default — tap the speaker/mute icon on the player.
  • On iOS, the physical Ring/Silent switch affects video audio in browsers. Flip it to Ring mode.
  • On Android, ensure media volume (not ringtone volume) is turned up.
  • The original video may have been uploaded without audio. Check if other videos on the platform have sound — if they do, this video may simply have no audio track.

HLS / Streaming Error Message

If you see an error like "Cannot load M3U8" or "Media Decoding Error":

  1. Hard refresh the page: Ctrl+Shift+R (Windows/Linux) or Cmd+Shift+R (Mac).
  2. Disable any ad blocker or privacy extension — some block CDN requests needed for HLS.
  3. Check if you're using a VPN or proxy that may block access to BunnyCDN's servers. Disable and retry.
  4. Try in Incognito/Private mode to bypass extension interference.
  5. Safari on older macOS may not support certain HLS variants — update to the latest macOS or use Chrome.

Mobile-Specific Playback Problems

  • iOS Safari autoplay: iOS requires a tap to initiate video playback. Tap the video to start it.
  • Android Chrome background tab: Videos may pause when switching tabs. This is an OS-level behavior — open SxyHub in a dedicated Chrome Custom Tab.
  • PWA fullscreen issues: If videos don't go full-screen in the installed PWA, try opening in the browser directly.
  • Data saver mode: Disable Chrome's "Lite Mode" / Data Saver — it compresses and breaks HLS streams.

Reporting Persistent Playback Issues

If video playback is consistently broken across multiple videos, it may be a platform-wide issue. Contact SxyHub Support with:

  • URL of an affected video
  • The exact error message (screenshot if possible)
  • Your browser, OS, and device type
  • Internet connection type (WiFi / mobile data)
